CAP .AND LINER ASSEMBLING MACHINE.

Application led July 23, 1926. Serial No. 124,412.

The present invention relates to machines for assembling caps and liners therefor, and aims to provide a novel and improved machine of that kind which is simple 1n construction and operation.

It is also an object of the invention to provide such a machine having novel fea.-

tures of construction to enhance the elficiency and utility thereof, and which may be adjusted for caps and liners of different diameters.

1With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides 1n the construction and arrangement of parts, as hereinafter described and claimed, it be ing understood that changes can be made within the scope of what is claimed without departing'from the spirit of the invention.

T he invention is illustrated in the accompanying drawings, wherein- Figure 1 is a plan View of the machine, portions being broken away and shown 1n section.

2 is a vertical longitudinal section on the line 2 2 of Fig. 1, portions being shown in elevation.

Figs. 3 and Il are transverse sections on the respective lines 3 3 and 4-4 of Fig. 1, portions being shown in elevation.

5 is a plan view of the liner supporting and guiding plates.

The machine comprises a suitable frame, which, as shown, has the table 10, and the caps 11 are fed onto said table from one side to a position below a stack of linersl 9. ris shown, the caps 11 are fed by gravity down a chute 12 leading from one side over one edge of the table to a forwardly extending cap channel defined by longitudinal guide bars 13 and 14 bearing on the table and extending to the front end thereof. The bar 13 is shorter than the bar 14 to provide an entrance iu rear thereof through which the caps move from the chutev 12 into the channel, and the bar 14 serves as a stop to limitthe movement of a cap when it enters the channel from the chute. The 'cap rests in an inverted position on the table 10 within the channel for movement forwardly in the channel. rl`he caps are usually of Sheet metal and have their rims formed with screw-threads or other means for attachment to the jars or other receptacles on which the caps are used, and the machine may be used for caps of different sizes, as will hereinafter more fully appear.

A liner magazine 15 is supported above the ltable at a point above the entrance or receiving portion of the channel defined by the bars 13 and 14, so that when a cap moves from the chute into the channel it will be positioned below the liner magazine. Said magazine comprises a horizontal plate 16 having a circular openingA 17 slightly larger than the liners 9 for the movement of the liners ydown through said opening. A vertical rod or post 18 vhas its lower terminal extending slidably through the plate 16 at the front edge of the opening 17 for the contact of the front edges of the liners. The rod 18 is adjusted vertically by means of a` screw 19 threaded within the plate 16 in front of the rod 18 and having its head engagging within a noteh20 in the rod 18, so that by rotating the screw said rod may be adjusted upwardly or downwardly accu rately. The lower end of the rod 18 may therefore be positioned to allow only the lowermost liner in the magazine to move forwardly under the rod 18 from the magazine. Opposite side rods or posts 21 forming with the rod 18 the walls of the liner magazine, have their lower ends secured to slides 22 movable in oblique slideways or channels 23 inthe plate 16, and the side edges of theliners 9 are adapted to Contact with the rods 21, whereby the vertical rods 18 and 21 guide the liners 9 for downward movement in the magazine to and through the openingl 17. rlhe slides 22 are clamped on the plate 1G by the clamping screws 24, and said slidesv have slots 25 receiving said screws, in order that when the screws are loosened the slides 22 may be adjusted inwardly or outwardly to decrease or increase the size of the magazine for liners of different diameters. As shown in Fig. 1, the liner magazine is adjusted for liners of the maximum diameter. By adjusting the slides 22 inwardly the rods 21 are moved inwardly and forwardly slightly so as to accommodate liners of smaller diameters. The stack or column of liners 9 may be readily placed in the magazine 15, and such liners may be of paper, cardboard, cork or other material, and are frequently coated or impregnated with wax or other substance.

A horizontal sheet. metal plate 25 rests on the guide bars 13 and 14 and extend under the plate 16 to provide a bottom for the liner magazine, the lowermost hner res e ing on the plate 25. Said plate is pro vided in front of the liner magazine with a circular opening 26 through which the hner mav move downwardly after being moved forwardly from under the magazine. The plate 25 has a longitudinal slot 27 ot narrower width than the diameter of the smallest liner for which the machine 1s 1ntended, extending rearwardly from the opening 26 to the rear end of said plate 25. The plate 25 is a liner supporting plate, and a liner guiding plate 23 is secured on the plate 25, and has an opening or slot 29 extending from its rear end to the forward edge of the opening 26 and of a width equal to the diameter of the opening 26. rlhus, the lowcrmost liner in the magazine resting on the plate 25 is guided forwardly within the -slot or opening 29 to the opening 26, and the rod 13 is adjusted to permit the lowermost liner in the magazine to move on the plate 25 under said rod, said rod 13 preventing the second or next lupper liner from moving out of the magazine, so that the liners` are delivered from the magazine one at a time from the bottom of the stack. 'lhe forward end of the slot or opening 29 being closed will also serve as a stop to limit the forward move- `ment of a liner when it reaches the opening 26. The plates 25 and 2S are secured on the bars 13 and 14 by screws 30 extending downwardly through said plates and bars into the table 10, thereby also clamping the bars 13 and 14 on said table.

llVhen the machine is adjusted for caps and liners of a smaller diameter than shown in the drawings, the slides 22 are adjusted as above indicated, and the bars 13 and 14 and plates 25 and 28 are removed and replaced by other bars and plates to accommodate the caps and liners of smaller size. Thus, by removing the screws 30, said bars and plates are readily removed from od the table so as to be substituted quickly and conveniently. f

The means for pressing the liners into the caps, includes vertical slide rods 31 at opposite sides of the bars 13 and 14 and opening 26, slidable through upstanding guides 32 having feet fastened by screws or bolts 33 on the table 10, and a transverse yoke 34 is fastened to the upper terminals of the rods 31. A tubular plunger stem 35 is screw-threaded through. the yoke 34 in a vertical position, and a llock nut 36 is threaded on said stem and bears against the yoke 34 to maintain the adjustment of said stem. A. plunger head 37 is engaged over the lower terminal of the stem 35 to move upwardly and downwardly through the opening 261 and a screw 37 entends through the stem 35 with its lower end threaded into the head 3f? and the head at its upper end bearing on the upper end of the stem 35, for securing the plunger head to said stem. Y y

The plunger head is reciprocated vertically, and for this purpose a transverse yoke 36 is secured `Ato the lower terminals of the slide rods 31, below the table 7, and is pivotally connected, as at 3.9., with one arm of a longitudinal lever 40 located below the table and mounted onv a transverse fulcrum or rock shaft 41 having its terminals journaled in hange-rs'42 depending from the table. rlhe rear arm of the lever 40 has a roller43 mounted thereon and working within a circumferential cam groove 44 in a drum or wheel 45 rotatable around a vertical pin or spindle 46 4below the table 10. The spindle 46 is secured in a U-sha `)ed bracket 47 secured to and depending from the table, and said bracket has a bearing 48 at one side to which a drive shaft 49 is journaled. 'lhe shaft 49 has a pulley wheel 50 thereon' for supplying power to the machine, and a bevel pinion 51 on the inner end of said'shaft meshes with the bevel gear teeth 52 with which the lower portion of the wheel 45 is provided, thereby rotating said wheel 45. The groove 44 is of such shape as to oscillate the lever 40 to raise and lower the plunger head 37 at the proper time in relation to the operation of other parts of the machine.

A feeding plumgeil or slide 53 is movable on the table 10 between parallel guide bars 54 secured on said table inrear of the liner magazine, and a depending pivot pin 55 carried by the slide 53 is connected by a connecting rod or pitman 56 with a crank pin 57 on the wheel 45, whereby the rotation of said wheel will reciprocate the slide 53 longitudinally on the table. longitudinal slot 58 in which the pin 55 works, and the slide 53 carries the pnshers or feeders for moving the caps and liners forwardly. y

rlhe cap pusher or feeder comprises a bar or plate 59 disposed longitudinally on the slide 53 and clamped on said slide by means of a clamping screw 60 threaded in the slide, the feeder 59 having a longitudinal slot 61 receiving said screw, in order that the feeder 59 may be adjusted longitudinally, when said' screw is loosened, thereby advancing thev cap to the proper position from below the liner magazine, when the slide 53 is moved for wardly. The forward end of the feeder 59 abuts or contacts with the cap 11 which is below the liner magazine, for moving .said cap forwardly to a. position below the opening 26, and the adjustment of the feeder 59 therefore enables the cap 11 to be moved forwardly to an accurate position below said opening 26. The feeder 59 moves under the plate 25.

rlhe liner feeder or pusher comprises a bar or plate 62 bearing on the cap feeder or bar 59,'and a screw 63y is threaded in the The table has a' lUU l plate 25.

feeder 59 to clamp the liner feeder 62v thereon, the feeder' 62 having a longitudinal slot 64 receiving the screw 63 in order that the feeder' 62 may be adjusted longitudinally to properly advance theflowermost liner from the magazine to the opening 26 when the slide 53 is moved forwardly. 'The clamping screw 63 is located' near the rear end of the feeder 62, and saidl feeder 62'fmove'sin the slot 27 of the liner supporting plate 25. The liner feeder 62 is adjustable for liners of differentthicknesses. Thus, an adjusting screw 65 is threaded in the cap feeder 58 below the liner feeder 62, and said liner feeder rests on said screw, so that by -adjusting the screw 65 upwardly 'the forward terminal of the feeder 62 is sprung upwardly so that the forward end ofthe feeder 62 will properly lengage the rear edge of the lowermost liner in the magazine to move said liner forwardly kunder the rod 13 to the opening 26. The screw 65 has an upstanding portion 66 of reduced diameter received in a longitudinal :slot 66 of the feeder62, and adapted for the engagement of a screw-driver or other implement for4 conveniently rotating the screw 65. Thus, the feeder 62 may be adjusted upwardly and downwardly according to the thickness of l' the liners, so as to feedonly the lowermost liner from the linermagazine, and the rod 13 will hold back the liners above.

In order to hold the'cap inl place below the opening26 for the proper reception of thel liner from above, friction pins 67 are slidable transversely in the bars 13 and 14 at opposite sides of the opening 26 and their inner terminals are V-shaped, as at 63, and project slightly from the inner sides of the bars 13 and 14, soA that the cap below the opening 26 is maintained in position between thetwo pins 67 at opposite sides. The outer ends ofthe pins 67 have flanges 69 within recesses 76 in the outer sides of the bars 13` and 14, and ksaid flanges have flat surfaces bearing-on the table 10, as seen in Figf4, to revent the pins 67 from rotating, so that their faces 63 are maintained in proper position. Coiled springs 71 are coniined between said pins and cover plates 72 secured removably7 to the outer .sides of the bars 13 and 14 across^the recesses 70, thereby yieldingly projecting the inner ends of the pins from said bars.` The pins preferably have recesses receiving the springs 71, as seen in Fig. 1, and the kpins 67 may yield when a cap is forcibly moved forwardly in the channel past said pins.

The plate 16 of the liner magazineis held by the rear bolts or screws 33, thereby supporting the liner magazine above the in operation, the cam groove 44 is so arranged with referencel to the crank pin 57, thatwhen the cap and liner feeders are movedv forwardly, the plunger head 37 is raised or retracted, and when the feeders are retracted or moved rearwardly, the plunger head is moved downwardly.v Starting with the parts in the position as shown Ic.

in the drawings, with the wheel 45 rotating in the direction ofthe arrow as seen in Fig.

3, as the crankpin 57 starts to move forwardly, the lever 40 is swung so as to raise the push rods 31 and 'depending stem 35 of the plunger head 37, thereby retracting l said plunger head upwardly above the opening 26. The feeders 59 and 62 being moved forwardly will result in the forward end of the feeder 59 contacting with the cap 11 below the ln-er magazine, while the forward end of the feeder 62 contacts with the lowermost liner in the magazine. Said cap is therefore slid forwardly on the table 10 below the plate 25 to a position below thel opening 26, while the liner is slid on the plate 25 into said opening, to drop downwardly through the opening into the cap.

When the cap is moved forwardly to posiy tion below the opening 26, it moves past the below the liner magazine by the lfeeder 59,

the first cap being advanced by the second cap, and beingshoved past the front pins 67, while the second cap is shoved by the feeder 59 past'the rear pins 67 to a position below the opening 26. Thus, as each cap is moved from below the liner magazine` to a position below the opening 26, the previous cap with the liner therein is ejected from the forward end of the channel between the bars 13 and 14. j

When the wheel 45 turns so as to retract the slide 53 and feeders 59 and 62, the lever 40 is swung by the wheel 45 to depress the plunger head 37, and said 'plunger' head moves downwardly through the opening 26 into the cap below said opening, to force the liner into the cap, as seen in Figs. 2 and 4. When the'feeders 59 and 62 have been completely retracted, as seen in Fior. 2, a cap 11 slides in front of the feeder 59 below the liner magazine, and the stack of liners 9 in the magazine moves down on the plate 25, `and the operation is repeated for each revolution of the wheel 45.
